Original application filed May 24, 1919, Serial No. 675,420. Patent No.1,403,075, issued January 10, 1922. Divided and this application filedMarch 8, 1921. Serial No. 450,654.

To aZZ whom it may concern:

Be it known that I, DANIEL T. GLAcKm, a citizen of the United States,residing in Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inManifold Sheets, of which the following is a specification.

This application, which is a division of my co-pending application,Serial No. 299,- 543, filed May 24, 1919, (now Patent No. 1,403,075,dated Jan. 10, 1922) relates to a multiform billing sheet adapted foruse in round-platen type-writing machines, and designed to furnish anumber of identical copies of each original bill.

Owing to the inconvenience of handling webs in typewriting machines,partly because of their slipping and creeping, it is advanta cons to beable to make out a number of hills upon a comparatively short integralsheet, thus avoiding these and other 'difliculties. It is however,troublesome to insert the separate carbon-sheets if a bill of the typedescribed is made out on a fanfolded sheet, inasmuch as such a sheetrequires that the carbon-sheets shall be inserted from opposite sides. I

According to the present invention, if a bill-head need not occupy alength exceeding 5 inches, it may be made out upon a sheet wrappedseveral times around the platen of the typewriter, there being wrappedtherewith, so as to be interposed between the layers, a carbon-sheet formaking the carbon copies. To enable this to be done rapidly andeconomically, the typewriter platen may co-operate with fingersextending far enough around its periphery to carry a work-sheet aroundthe top of the platen as it rises from the (printing point, and thenbend it backwar ly and down wardly to the usual rear feed-rolls, therebyreintroducin the work-sheet between the platen and t e feed-rolls.

Other features and advantages will hereinafter appear. 7

In the accompanying drawings,

Figure 1 is a perspective view of a billhead and its four carbon copiesshown removed from the platen when written out and before thecarbon-paper is removed therefrom.

.Figure 2 is a vertical section through the platen and its cowoperatingfingers, the'billhead being shown in position for typing.

Figure 3 is a diagrammatic perspective view, showing'the bill-sheetwrapped once around the platen.

Figure 4 is a similar view, showing it wrapped twice around the platen.

Figure 5 is a similar view, showing it wrapped three times around theplaten.

Figure 6 is a diagrammatic perspective view, showing the bill-headpartly written out, and broken away to show how the writing issuperposed.

A platen 1 is fixed upon an axle 2 adapted to be journaled in the endwalls of the usual typewriter carriage (not shown), as in the Underwoodstandard typewriter. When it is desired to make out a bill of the classdescribed, that is, to provide one original bill and several copies, asheet 6 is employed. The sheet 6, as shown in Figure 1, is folded sothat one bill-head copy 8, which is printed upon the back of sheet 6, isfolded over upon a carbon-sheet 9 which lies at the back of the rest ofthe sheet 6 (that is, the sheet minus the billhead copy 8). lhebill-head copy 8 has a length equal to the circumference of the platen.It will be seen that the sheet comprises an original bill-head 11 andcopies 8, 12, 13 and 14. Where the copy 8 is folded over, there isformed a leading edge 10. The carbon-sheet 9 lodges between sfheets 8and 11 which form a pocket there- The leading edge 10 is inserted aroundthe platen 1 in the usual manner, and the sheet 6 is held against theplaten while the latter is turned, thus winding the sheet around theplaten until the edge 10 is reintroduced at the rear thereof (see Figure3). Upon further rotation of the platen, the bill-head copies 12, 13 and14 will be wound around the platen and superposed one on the other. Itwill be seen that, as a result of the folding back of the forward end ofthe sheet over the leading end of the carbon-sheet 9, the latter will beheld in osition with reference to sheet 6 when said sheet is inserted inthe machine. It will be seen also that until the Figure 3 position isreached the carbonsheet lies between copies 8 and 11; in the Figure 4position the carbon-sheet lies also between copies 11 and 13; and in theFigure 5 position between copies 12 and 13,

the platen. nearly to or below the level of the platenetc. By enclosingthe leading edge of the carbon-sheet between the copies it is keptout ofcontact with the platen or the feedrolls 19 and 20, such contactresulting in'wrinkling of the carbon-sheet as is well known to typists.In order that the co ies when wound upon the platen may have t ieiridentical lines superposed, the successive copies of the sheet 6,forming the bill-head copies 12, 13 and 14, are slightly longer, thedifference amounting to less than one-- sixteenth of an inch in manykinds of paper, but depending upon the kindof paper used. Thissuccessive increase in length is necessary if the writing upon thebill-heads is to fall at identical spaces thereon, because, when thefirst bill-head is wrapped around the platen, its outer surface is of acircumference slightly greater than that of the platen, and thisincreases with each superposed thickness of the bill-heads. Thus, thetop line 16 of cop 1 12 will coincide with edge 10, top line 1 of copy13 will coincide with line 16 of copy 12, top line 18 of copy 1-1 willcoincide with line 17 of copy 13, etc.

To aid in winding the sheet around the platen and holding the sheet incontact therewith, paper-fingers 22 are provided adjacent the platen.These fingers may extend down to the printing line or even down belowthe usual wing-scale 21 substantially to the front feed-rolls 20, thefingers being supported from a transverse rod 23 which extends betweenthe end walls of the carriage (not shown). Each finger is supported fromthe rod 23 by slidable brackets '26, which embrace the rod and are heldagainst revolving thereon by a key 27 held in a spline 28 on the rod bymeans of a spring 29 of a common form which stretches between the twobrackets 26. The brackets are connected by a plate 30, and one of themcarries an extension 31 having an elbow 32 to which a finger 22 issecured, as by rivetmg.

In order to guide the leading edge 10 downwardly behind the platen tothe bite of the rear feed-rolls 19, thereby insuring the reintroductionof said leading edge between the platen and the feed-rolls, there isprovided a second set of fingers 33 forming extensions of each finger22, which are curved so as to fit closely the periphery of The fingers33 extend down axle 2. In order to provide the flexibility of thefingers 33 needed to permit the fingers 22 to be swung up around the rod23, the fingers 33 are each mounted upon a pivot 34 on the elbow 32 andare held against the platen by a s ring 35 which is sufiiciently.

strong to con no the leading edge 10 to the )urface of the platen afterthe platen is urned rapidly, but which, nevertheless, can

increase of the circumference be swung easily enough to permit thefingers 22 to be swung up.

Variations may be resorted to within the ranged in succession from topto bottom 7 of the sheet, the length of each form being substantiallythe same as, the circumference of the platen on which they are to bewound, the length of the forms being progressively increased from top tobottom so as to enable the outer forms to re 'ster, with the inner formswhen wound a out the platen, and
